Noise-cancelling technology is typically the quarry of over-the-ear headphones, but the new Beoplay E4 headphones bring Bang & Olufsson's celebrated sound technology to the earbud. The new headphones make use of an improved version of the tech in Bang & Olufsson's Beoplay H9 headphones, an over-the-ear model that offers immersive noise-cancelling.
Since the Beoplay E4 earbuds offer such a powerful noise-cancelling system, the company had to find a creative way to quickly turn it on and off. After all, the peaceful isolation of noise-cancelling while listening to music also means that users are somewhat disconnected from the outside world. Rather than forcing them to pause their music or pull out the headphones, the Beoplay E4s can be controlled via gestures, allowing users to activate 'Transparency Mode' quickly and easily.
